ATTACHMENT FOR MOTOR CYCLES.

Y Application filed June 21,

To all whom it may concern Be it known that we, HARRY Gr. Eran and CLEO H. Cairns, citizens of the United States, residing at Topeka, in the county of Shawnee and State of Kansas, have invented certain new and useful Improvements in Attachments for Motor Cycles, of which the like.

A further object'of the invention is to provide a device of this character which niav be readily attached'to and detached from a motorcycle.

A still further object of the invention is to provide means whereby the motorcycle rider is held upon lhisseat in the event of overturning or a collision of the motorcycle. Another object of the invention is to provide a device of this character which may bel applied to a motorcycle without materially altering the construction thereof.

An additional object of the invention is to provide a device of this character which is simple in its construction, durable in service and a general improvement in the art.

These and other objects we attain by the construction and arrangement shown in the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of our invention and wherein like reference characters designate like parts throughout. l

In the drawings Figure 1 is a side elevation of a motorcycle having an attachment constructed in accordance with our invent-ion;

Figure 2 is a plan thereof;

Figure 3 is a similar Vview of the attachment removed from the motorcycle;

Figure 4 is a section on the line 4 4 of Figure-5 is a detail perspective view showing the mountings of the ends of the support.

F igurel 6 is a fragmentary perspective of the machine taken from the right-hand side 1922. Serial No. 569,825.

thereof and illustrating particularly the parts associated with the side car chassis.

Figure 7 is a fragmentary sectional view taken on the line 7-7 of Figure G; and

Figure 8 is a detail sectional view showing the mounting of the foldable foot board 50.

Referring now inore particularly to the drawings, the character M designates a motorcycle as a whole, which is illustrated in the present instanceas having secured thereto a side carchassis C. This side car chassis, as well known to those familiar with the art, consists of an axle 1() secured at one end, as at 11, to the rear end ofthe motorcycle frame at one side of the drive wheel of the motorcycle. From the axle 10, which is provided at its outer end with a supporting wheel lV, a' brace 12 extends forwardly in substantially parallel relation to the motorcycle M and has its forward end turned toward the motorcycle and secured to the forward brace 13 of the engine support of the motorcycle. To the inturned end of the brace l2 is secured a second rearwardly eX- tending brace la which inclines outwardly from the motorcycle and has its rear end secured to the axle 10 adjacent the wheel bearing end thereof.- The numeral 15 indicates a spring bracket of the chassis C which is secured to the braces 12 and 14 and eX- tends outwardly from these braces and is provided at-its outer end with a rearwardly extending brace 1G, the rear end of which is secured to the wheel bearing end of the axle 10. |The parts 1() to 16 inclusive constitute a motorcycle side car chassis of usual construction and form no part of our invention 'out arc employed for supporting the protecting cage. will hereinafter appear.

The numeral 17 indicates a bar paralleling the motorcycle M at the opposite side thereof from the chassis C and having its forward end 18 turned inwardly and engaged with the brace 13 in substantially the same manner as this brace is engaged by the brace 12 of the chassis C. The rear end 19 of the bar 17 is likewise turned inwardly and is engaged with the rear end of the motorcycle frame in substantially the same manner as the axle 10 is attached thereto but at the opposite side of the drive wheel therefrom. The numerals 20, 21 and 22 designate arcuately curved diverging brace bars having their upper ends secured to a plate P in any suitable manner and their lower ends engaged with .the bar 17, the braces and 22 being engaged with the bar 17 adjacent the torward and rear ends thereoic and the brace 2l beingengaged with the' bar 17 approximately centrally thereof. The cent al or belly portions ot' the brace bars 20, 21 and 22 are connected by bracingand spacing elements 23.

Secured to the spring support l5 adjacent the outer end thereo'iI and extending rearwardly and over the axle l() is a support 24, the rear end oi which is disposed rearwardly ol the rear end ot' the wheelli'T of the chassis (l. Secured to the brace l2 or' the chassis and to the support bar 2l in advance oft the wheel ll' is a transverse support bar 25, the outer end ot which projects beyond the outer tace ot the wheel ll' and has secured thereto a rearwardly extending supporting member 2T, the rear end of which turns inwardly and is secured to the rear end of the bar 2l. lt will be seen that the support 2i. the .outer end oli' the support and the support. 2T combine to form a framework sari-minding the wheel lV. The numerals 29, :in and 31 indicate arcuately curved brace bars corresponding to the brace bars 20, 2l and 22 but extending to the opposite side of the motorcycle M there-trom. The lower end ,ot the forward right hand brace bar 29 is secured to the angular brace 14 of the chassis C and the belly portion of this brace bar is connected with the belly portion of the torward brace bar 2() at the left hand side of' the machine by a b ace rod 32 which is adjustable as to length. The central brace bar which is substantially aligned with the brace bar 2l of the left hand side of the cage has its lower end secured to the spring bracket l5 adjacent the outer end thereof and is connected at its belly portion with the belly portion ot' the brace 29 by means ol a rigid spacing and connecting bar 33. The rear right hand brace bar has its lower end Secured to the end 2S oi' the support 2T at the junction thereotl with the brace 2li and is secured at its upper portion at a point near the plate P to a corresponding point on the brace 30 bya forwardly extending brace The rear right and lett hand braces 22 and 3l of the rage are connected by a. spacing and bracing bar 35 which is adjustable as to length.

The plate l? is rigidly connected with the chassis (l by means ot' a vertically extending brace 36, the lower end of the b ace beingl engaged with the spring bracket or support l5 adjacent the inner end thereof and between the braces l2 and 1l oi the chassis so vthat a very rigid support is provided. The

upper ends ot' the braces are held in position upon the plate P by means of a second plate l?I superposed thereon and secured to the plate P and braces 20, 2l, 22, 29,

: and 3l by means of bolts or the like. Secured to the forward end 18 of the bar 1T and extending first downwardly and then inwardly and rearwardly thereform is a guard 3T, the end ol which is engaged with the lower engine support member 58 of the motorcycle iframe.'

The -main changes in the construction otV the motorcycle proper consist in the removal of the seat thereotl and the provision of a shock absorbing pad 39 secured upon. the tank 'l et the motorcycle and upon which the rider of the motorcycle is ada-ptedto rest, and with the shifting of the gearshit lever -l-O l'trom its accustomed supporting bracket al to a point further forwardly upon the tank in order that it may be more readily accessible to the driver when resting upon the pad 32). le likewise provide the front iorl l4l oi the motorcycle with guard strips l2 adapted to engage the tank'llof the motorcycle M prior to the engagement of the operators hands when in position upon the handle bars H with the tank so as to prevent mashing of the lingers duringan upset of the cycle or a sharp turn, it being understood that when the operator is lyingupon the pad 39 the handle bars H must neces sai-ily be positioned forwardly well down as they are usually mounted inracing. Secured to the post or standard 36 at one end as indicated at 36 and to the braces 23 at the u opposite end are canvas strips i3 which,

when the driver is in position upon the pad 3S), will extend immediately over his back and eti'ectually prevent him from being thrown against the brace bars of the cage when the motorcycle is upset. As an addi-V tional precaution for the safety or' the driver,

we secure to a rigid portion at the rearend oi.E the motorcycle M and preferably to an ordinary luggage carrier Llei, one end of a safety strap lle', the opposite end of which is adapted t'or engagement with a belt worn by the driver and which will prevent the driver being thrown 'forwardlly upon the pad. f

. Suitably secured to the chassis C of the side car and to the brace 27 is a mallet mans seat lo straddling the wheel lV and connectedV with the outer vend of the support 25 by means ol' a -forwardly and downwardly extending arcuate brace 46. vThis seat 45 is adapted to be occupied by the man wielding the mallet in playing a game oi polo and has extending downwardly therefrom and secured to the supports 25 and 2T wire netting l-enclosing t-he upper portion of the wheel lV so that his legs may be protected fromV ac cidental engagement therewith. Arranged upon the chassis C inwardly of the wheel lll" is a platform 48 which is provided with an angularly disposed foot rest 49 against which the inside foot of the mallet man may be engagedv to prevent its slipping upon the plat- V form. To the support 27 are secured a folding foot support and a rigid plate 5l adapted to support the chassis C in event of a right hand turn over of the machine and prevent injury to the outer leg of the mallet man. The mallet mans seat, it will be noted, is arranged in an exposed position permitting him to jump from the machine in the event of overturn unless the overturn is very rapid and a right hand turn. In order that the mallet man may suitably brace himself, he may either engage his hand with the brace 34 connecting the arcuate braces 3() and 3l at the left hand side of the machine or with a transverse brace 52 connecting the belly portion of the brace 30 with the upper end portion thereof.

It will be seen that the structure hereinbefore described provides a cage substantially circular in cross section adapted to receive and substantially enclose a motorcycle and a side car frame attached to the motorcycle. It will also be seen that this frame embodies means for protecting the driver of the machine and maintaining him in position upon his seat. The brace 37 hereinbefore described effectually prevents the engagement of the foot board 53 at the left hand side of the machine with the ground and accordingly prevents this foot board from being folded up against the drivers foot. Means are further provided for preventing mash ing of the driversfingers and for providing for the easy escape of the mallet man from his seat in the event of an overturn. If the machine be overturned either to the right or the left, it will roll upon the arcuate braces and may be readily returned to its proper position if it does not do so automatically, the wheels of the motorcycle and the Wheel W of the side car chassis providing a three point support which will ordinarily check the overturning movement, leaving the machine in the proper position upon the ground.-

In case of a forward overturn occurring when making a right hand turn, which is a comjmon occurrence where a side car chassis is attached to a motorcycle, the force of the fall Vwill be taken by the brace 3() and the machine may be readily righted.

From the foregoing it is believed to be obvious that an attachment constructed in accordance with our invention is particularly well adapted for the purpose for which it is intended for the reason that a complete protection for the driver is afforded and for the reason that it may be readily attached to or detached from the motorcycle when this is desired. It will furthermore be obvious that the construction thereof as hereinbefore set forth is capable of some change and modification without materially departing from the spirit of our invention and we accordingly do not limit ourselves thereto eX- cept as hereinafter claimed.
